Job description

Application close date

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! This role supports the development and operations of New Glenn, a single-configuration, heavy-lift orbital launch vehicle capable of routinely carrying people and payloads to low-Earth orbit, geostationary transfer orbit, cislunar, and beyond. Its first stage is fully reusable, and the vehicle was designed from the beginning to be human-capable. As part of a small, accomplished team of engineers, this role carries full-lifecycle ownership of guidance, control, and sequencing algorithms from requirements definition through flight. The position spans algorithm design, flight software implementation, performance and robustness analysis, verification, and hardware-in-the-loop integration.

Responsibilities

• Design and develop guidance and control algorithms for New Glenn flight control
• Sequence mission activities and vehicle system commands
• Develop GN&C requirements with flow downs to subsystem and software levels, including companion verification methods
• Build guidance and control algorithms in Simulink to support auto-code generation to target
• Implement hand-coded flight software in C/C++ where appropriate
• Conduct stability and performance assessments including development of linear and nonlinear models
• Perform Monte Carlo simulation campaigns to characterize algorithm performance and robustness across dispersed environments
• Author and execute unit tests, ensure code coverage standards, and support formal verification activities
• Support hardware-in-the-loop integration and test campaigns
• Validate plant models and algorithm performance using test and flight data
• Coordinate cross-team vehicle-level analyses and trade studies
• Lead root cause investigations and peer reviews of GN&C products

Minimum Qualifications

• BS in Aerospace Engineering, Mechanical Engineering, or related field
• 7+ years experience developing G&C software for aerospace, automotive, or other safety-critical applications
• Proficiency in MATLAB/Simulink for algorithm design and analysis
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum

Preferred Qualifications

• MS or PhD in Aerospace Engineering, Mechanical Engineering, or related field
• Experience with AI-assisted software development workflows
• Demonstrated knowledge in both classical and modern control design techniques
• Experience with C/C++ flight software development
• Experience with auto-code generation from Simulink models
• Monte Carlo analysis and statistical methods for performance and robustness characterization
• Experience supporting hardware-in-the-loop or flight test campaigns
• Python scripting for analysis, automation, or data processing
• Experience with plant model validation using test or flight data
• Familiarity with flight software verification processes (unit testing, code coverage, requirements traceability)
• Experience mentoring junior engineers or leading technical trades across disciplines
